Here you go.
First, the server has to support X. In /etc/ssh/sshd_config you
should have:
X11Forwarding yes
#X11DisplayOffset 10
X11UseLocalhost no
XAuthLocation /opt/xorg/bin/xauth (if Xorg is installed in /opt)
If a change is needed, reload sshd. (/etc/init.d/sshd reload)
On the client side:
~/.ssh/config

Host 192.168.1.22 (ip of remote or name is in /etc/hosts)
ForwardX11Trusted yes

If you run 'ssh -v remote', you should see
debug1: Requesting X11 forwarding with authentication spoofing.
Do NOT change DISPLAY. You do not need the xhost command either. The
sever will set DISPLAY to
remote:10.0
If you have multiple sessions, it will change to remote:11.0, 12, 13,
etc.
That's what the default X11DisplayOffset above does.
Then just run something like xclock and it should come up on your client.
Note that gtk+3 based apps will not display properly. They don't look
up settings on the remote system and look horrible, although they do
run. I think they need something on the local system, but I have yet
to figure that out. ineresting
You can also troubleshoot the sshd daemon. You have to run on the
remote system '/usr/sbin/sshd -d' and it puts debug info to the
screen and the daemon does not go to the background. That's how I
figured out that XAuthLocation was needed.

Bruce,
I find all this VERY interesting. I was surprised to see the
UseLocalHost set to no. Both sides on my machines were set to yes. There
were some other things I changed in the config files like mine had PAM
turned on and I don't use PAM. None of that seemed to make a difference.
I did the ssh -v and the sshd -d and didn't see the XAuthLocation you
saw. But since I tried everything else you have here and it still wasn't
working I included a line like you have here even though there was no
such line in the file. The others were all there although some were
commented out and needed to be UN-commented and changed. I added the
xauth line with the usr/bin/xauth path and restarted sshd. Works like a
charm. Thank you so much for helping me work through this. It will help
greatly.
And thanks to all the others who sent me links and copies of the
post. I will now have to go look at the archives again and try and find
out why I couldn't find the post. The way the page reads it sounded like
using the search would work best so that is what I did. I searched on
the subject line and it brought back nothing of what I wanted to see but
it did bring back a lot of posts from the right time frame. I didn't see
anywhere I could tell which list to search but I probably missed that
like I have other things. :-( Thanks again to all.
Arnie
